CUTTING-OUT AND MOLDING MACHINE.

Specification of Letters Patent.

Patented Feb. 13, 1912.

To all whom it may concern:

Be it known that I, ERNEST.LOUIS POUR- TAUBORDE, of 13 Rue du Faubourg Montmartre, in the city of Paris, Republic of France, engineer, have invented a Cutting- Out and Molding Machine, of which the following is a full, clear, and exact description.

The present invention relates to a machine for molding and cutting out, according to certain patterns or models, objects of any desired shape, such as countersinks, granite walls, or stones by means of rotating steel tools.

The machine can be used for working materials of all kinds but is especially adapted to hard substances such as marble, onyx, granite and the like.

The machine is essentially characterized by the following features:

First, the arrangement and method of mounting the supports on which are fixed the model and the work, so that the supports can be inclined simultaneously, and in parallel during the operation to form angles which can be varied at will both in a vertical and in a horizontal plane, the movement of the supports being manually controlled.

Second; the method of mounting the tool whereby it may be brought into contact with the work by the pressure of the hand upon a conveniently arranged lever. By reason of this arrangement of the supports and of the tool, the operator is able to diminish or prolong the time of contact of the tool and to vary the pressure of the tool at different points of the piece to be produced, from which results the following: First, an increased production; second,making it possible to cut out or mold in different planes very delicate parts which could not be made by hand.

The invention is shown in the accompanying drawings in which,

Figure l is a face view of the machine. Fig. 2 is a side view. Fig. 3 is a plan view corresponding to Fig. 1. Fig. 4 is a horizontal section on the line AA of Fig. 2, and Figs. 5 and 6 are detail views.

As shown in the drawings, the present machine is provided with a vertical frame a, on which can vertically slide a carriage b. This carriage is mounted in the same manner as the carriages of the machine for the countersinking of metal, or of machines for molding marble, that is to say, the carriage can be moved easily by hand under the action of the counterweight, and it is stopped afterward at the desired height by a nut on which it can lie. This nut can be moved on a vertical shaft, which is screw threaded for that purpose.

A second carriage c is mounted for vertical movement in the wedge shaped guides cl, carried by the carriage b (Fig. 4) and the said carriage c is retained in its uppermost position by means of a laminated spring 6 fixed at its center on a vertical support f, forming a part of the carriage b, (Fig. 3).

The two ends of the spring are united by a cord or flexible wire 9 on which is placed a pulley k mounted on the end of a vertical rod 21 forming a part of the carriage c. The carriage c carries the tool operating on the material as well as the blunt point which serves as a guide.

A metallic arbor j passes through the entire height of the carriage c, the lower end of the arbor receiving the proper tool (Fig. 5) and the said arbor may receive a rotary movement of variable speed by means of a belt passing over the pulley Z0 fixed to the upper end of the said arbor, or in any other suitable manner. The blunt guide is also carried by a vertical arbor Z passing through the carriage 0, and the arbor Z can be moved vertically by means of a toothed wheel m, operated by a hand wheel m, and engaging on a rack n fixed on the arbor Z. The latter can be afterward maintained at the desired height by any retaining device, for example by means of a screw the end of which would press on the shaft 1. The contact of the tool and of the blunt point with a piece can be secured on the carriage b by means of a pressure screw 7) operated by a hand wheel p and engaged in an opening a, in

the carriage 0. Below the carriages 7) and c are placed two other carriages q and r, the said carriages being superposed as shown in Figs. 1 and 2 of the drawing, and can be moved at right angles to one another, the carriage r by running on rails placed on the ground, and the carriage q by running on rails carried by the carriage 7.

On the upper carriage g are placed two horizontal supports 8, s, on which are fixed in any suitable manner, the work t, and the model t. The supports 8, s are mounted on trunnions u, suitably supported by the lugs u fastened to the ends of the bed plate 1; placed on the carriage q. The supports can be inclined simultaneously and in parallel, and at any angle, by means of two worms w, w, carried by a horizontal worm shaft 10 and acting on two worm wheels as, and m, fixed on the supports 8, s. The shaft being operated by a hand wheel ta The plate or bed 11, on which are mounted the supports 8, s, is articulated at one end 011 a shaft 0), and can be moved in a horizontal plane by turning on its axis under the action of an endless screw 3 controlled by a flywheel 3/ and engaging with a rack z, placed at the other end on the bed '2). The arrangement of the carriages and 1* and of the bed 4) is therefore such that the work 6 and the model t can be moved in any direction simultaneously and in unison, whereby to bring them in any desired position in contact with the tool and the blunt guide carried by the carriage 0.
